I have used this jersey once, but in a really warm day and it's amazing! It's really breathable and you can barely feel the moisture, it's rapidly wicked away from the skin.
The fit is more relaxed compared to another jerseys I own specially at the bottom, but I really love how it fits and it's really comfortable.
The pockets are perfect, really spacious perfect to carry energy bars, your cellphone or your GoPro (or all of them).
I bought the orange one and loved the color since the beginning, it also provides a nice visibility in low light conditions, because of both the color itself and the reflective bands it has in the sleeves and the back.
